Christmas in Cambridgeshire

The supermarket employee, who wanted her identity and the Tesco location to be kept anonymous, said: "So we put advent calendars out on sale on the third week of August.

"Most customers come and have a look and make some wisecracks. About 80 per cent of those wisecrackers pick something up and buy it.

"This morning I had a customer ask me for Christmas tree lights that we had run out of a few days ago. Then a lady asked me for advent calendars.

"I explained that we'd got heavily reduced "free from" advent calendars but that was all we had left this late in the game.

"She said her child wanted a specific one and it was my fault that the child would have to go without, I'd ruined Christmas and a few choice words thrown in. Of course I apologised for not having any left, and suggested she could buy some chocolates instead but that wasn't what she wanted to hear.

"I didn't rub it in and tell her they were reduced to clear three weeks ago but I wanted to as she deliberately shoved her trolley into me as she stomped off.

"We are used to this, it happens every year. It didn't hurt, and we waited until she was out of the aisle before we had a good giggle about it..."
